About TinyKit
31 free developer tools that run 100% in your browser
TinyKit is a free collection of 31 online developer tools that run 100% in your browser — encoders, decoders, converters, generators, and utilities covering Base64, URL encoding, UUID and ULID generation, JWT decoding, cryptographic hashing, JSON formatting and conversion, YAML to JSON, CSV conversion, cron expression building, chmod calculation, HTTP status lookup, HTML entity encoding, and more. Everything executes client-side with zero server round-trips: no sign-up, no cookies, no tracking, and nothing you paste ever leaves your device, which makes it safe for pasting secrets, tokens, and internal data during development. Each tool is a single static page that works offline once loaded, loads in milliseconds, and is fully responsive on mobile. TinyKit also ships a free REST API with 24 endpoints (1000 requests/day per IP, no key required) mirroring the same utilities for scripts and automation, plus an MCP server exposing every tool to AI coding assistants. The site requires no account and carries no paywalls — every feature is free forever.
